CAPE CANAVERAL, Fla. — The rocket that can launch the subsequent people to the moon is rolling to the pad for its historic mission, which might raise off just some weeks from now.
NASA’s House Launch System (SLS) rocket, constructed to assist the company’s Artemis 2 mission and usher in a brand new period of crewed flights to the moon, headed out from the Car Meeting Constructing (VAB) right here at Kennedy House Middle (KSC) in Florida this morning (Jan. 17), starting a 4-mile (6.4 kilometers) trek to Launch Complicated-39B (LC-39B).

SLS stands 322 ft (98 m) tall and weighs roughly 2,870 tons (2,600 metric tons) when absolutely fueled. The rocket is powered by two house shuttle-era stable rocket boosters (SRBs) stacked 177 ft (54 m) tall on both aspect and 4 RS-25 engines, additionally initially designed for the house shuttle. Mixed, they produce 8.8 million kilos of thrust at liftoff to ship the rocket’s higher phases and Orion crew capsule to house.
Shifting slower than 1 mph (1.6 kph), the huge automobile’s journey from the VAB to LC-39B is anticipated to take eight to 10 hours. As soon as it is on the launch pad, NASA will spend the approaching weeks performing techniques integrations and automobile checkouts forward of a fueled launch countdown simulation generally known as a moist costume rehearsal, and, if all goes based on plan, a launch try in early February.
NASA is focusing on Feb. 2 for the moist costume rehearsal. Feb. 6 is the earliest potential launch day for Artemis 2, which can fly NASA astronauts Reid Wiseman, Victor Glover and Christina Koch and Canadian House Company astronaut Jeremy Hansen aboard the Orion spacecraft on a roughly 10-day mission across the moon.
The launch date is basically depending on how techniques checks go as soon as SLS reaches the pad, nonetheless, with backup launch alternatives mapped out by means of Feb. 11 and extra home windows in March and April.
Artemis 2 is the second mission of NASA’s Artemis program and would be the first to fly a crew aboard Orion. Artemis 1 launched in November 2022, after a checkout marketing campaign that ended up lasting many of the yr. After its debut rollout in March 2022, the Artemis 1 SLS moist costume rehearsals and launch makes an attempt have been tormented by cryogenic hydrogen leaks, climate delays and different components that resulted in three journeys again to the VAB for upkeep.
NASA officers are hoping to keep away from an identical marketing campaign with Artemis 2 and voiced confidence within the rocket’s readiness and optimism a few launch within the February window.
When it launches, SLS will ship Orion to Earth orbit, the place the Artemis 2 crew will carry out techniques checks forward of a translunar injection burn that places them on target for the moon. That burn will likely be accomplished by SLS’ interim cryogenic propulsion stage, which Orion and its service module will detach from to conduct proximity maneuvering checks on their approach to lunar house.

The Artemis 2 astronauts will not go to lunar orbit. As an alternative, the mission will fly a “free-return trajectory” that loops the capsule across the moon and slingshots it again to Earth no matter any anomalies the crew or spacecraft might encounter through the mission. The flight path ensures the secure return of the Artemis 2 crew and Orion, with out the opportunity of a malfunction stranding them in lunar orbit.
Artemis 2 is the subsequent step in NASA’s aim to return astronauts to the lunar floor, the place the company hopes to ascertain a base within the moon’s south polar area. Artemis 3 would be the first mission designed for a lunar touchdown, however it can proceed provided that Artemis 2 is profitable.
Artemis 2 will likely be as a lot a proving floor of Orion’s life assist techniques as Artemis 1 was for the spacecraft’s core design. Any sudden pace bumps through the upcoming mission might trigger additional delays for Artemis 3, the anticipated launch date for which is already starting to slide previous NASA’s hopeful 2027 goal.
Artemis 2 crew members have been coaching at KSC, conducting launch-day rehearsals over the previous a number of months in preparation for his or her mission, and have been current to see their SLS rocket roll out for the primary time in the present day.
